Tahm Kench: The River King. Terrifying and horrific river monster, or just an over feed guppy?

After watching his/ it's reveal video. The ideas I received from the new champ Tahm Kench are quite similar to to a sci-fi horror movie. Something like Creature from the black lagoon, or swamp thing. Although I'm loving the idea of this champs and its abilities. It just seems as though he could do more, and Tahm seems to lack that extra little essence to make him that monster I so dream to see in The Rift. I think it would be cool it they incorporated the the Q, W combo with enemy champs. I feel as though it would give him even more or a presence within team fights. Being able to do playmaking pick with a skilled Q, W. I feel as though it would make him more of a threat, and to create great zoning potential since he's is suppose to tank. In the Essence of a Nautilus, Blitz, or even Amumu. We all know that terrifying feeling of getting pulled by either one of those champs. He seems like the kind of champ that follows those same nightmarish core values. I feel as though right now he's pretty linear right now, but don't get me wrong I love my linear champs ie Garen, leona, Voli, but It just seems with this champ he could do soo much more. Being a representation of a demonic deity in which creates the many folklore and tales of river monsters, plus I feel as though it would go with his video and lore.
